摘要
表贴式自循环蒸发冷却技术凭借其高效冷却特点在电力电子设备中拥有广阔的应用前景。为提高冷却系统可靠性,避免在运行过程中流动不稳定性可能产生的不利影响,以表贴式自循环蒸发冷却系统流动不稳定性问题为研究目标,搭建相关实验平台,探究表贴式自循环蒸发冷却系统中存在的流动不稳定现象及其发生机制,并分析了系统压力、液位、并联支路数对表贴式自循环蒸发冷却系统流动不稳定性的影响规律。研究结果表明:在表贴式自循环蒸发冷却系统中,增大系统压力、提高系统液位均有助于提高系统的稳定性,这对电力电子模块高效换热冷却方案的选择有借鉴意义。
Surface-mounted self-circulating evaporative cooling has a broad application prospect in power electronic equipment manufacture.To improve the reliability of the cooling system and avoid the flow instability that may cause an adverse effect during operation,a flow instability experimental platform was built to explore the flow instability and its mechanism,and to investigate the influence of system pressure,liquid level,and branch number on the flow instability.Results show that increases in system pressure and liquid level could enhance the stability of the system,which offered a reference for the cooling scheme selection of power electronic module.
